L:ike you said " NO tire maker wants to or is willing to address this in reagrfd to trikes" The mounting of a tire in reverse seems to be fairly common and in many cases makes the trike handle a little better * although how so i have no idea on* and in some cases its a mater of " it just feels better" to the driver.
I have found that on Sough Texas rough roads i got a lot of rattle and jarring and when i put a shim in the anti dive valve that jolting / jarring completley went away. YES there is a little more front end dip when i pt on the binders but nothing shockingly so.
The main reason i posed the ? about mix of tires on trikes is that i have whitewall Radial tires on the back and would like to compliment them with a WW tire up front and there is only 1 tire maker who makes a double sided WhiteWall tire that will fit the Wing.......
